Rangefinders (landing page)¶
Copter/Plane/Rover support a number of different rangefinders including Maxbotix Sonar and Pulsed Light LED range finders.
Downward facing Lidar are used in flight modes which have height control, such as Altitude Hold, Loiter and PosHold Mode. The data from the sensor will be used until you exceed RNGFND_MAX_CM, after that it switches to the barometer.
Copter-3.4 (and higher) includes support for Terrain Following in Auto mode.
Copter-3.5 (and higher) can use lidar for object avoidance.
